mPEG11-COOH, also known as mPEG11-acid, is a type of monodispersed mPEG terminated with a carboxylic acid functional group (COOH). The carboxylic acid group provides a reactive site for conjugation with primary amines or other nucleophiles, enabling the attachment of the mPEG11-COOH molecule to proteins, peptides, nanoparticles, or other surfaces via stable amide bond formation.
